To all' whom t may concern:

Be it known that we, Janine llt.' Amusrnone and THOMAS B. Wvun, citizensot the United States, residing at Pittsburgh and Bellevue, respectively,in the' county of Allegheny and State oit Pennsylvania, have inventedcertain new and usetul improvements in integrating and RegisteringDevices for F luid li/ieters, of whichthe following is aspecication. .4

rlhis" invention is for an integrating and registering device for duidmeters, which device is designed to automatically register the volume ofa uid passing througha pipe in units of a constant value irrespective ofvariations and uctuations in the pressure and velocity ot the fluid,Aand relates particularly to a device :tor use in connection withoriiice meters, Pitot meters, and others.

lt is a well known tact that the density of a gas increases with thepressure and that a given volume or gas at two atmospheric pressureswill be double the amount at a single atmosphere. ln our co-pendingapplication Serial No. 461,458, filed April 14C, 1921, we have describeda device for measuring the quantity of gas at a given pressure, i. e.,the

` pressure at which it is to be used or sold,

irrespective of the pressure in the pipe line.

ln the said application, the gas passes through an ordinary meteringdevice, which metering devicecontrols the operation of gearing, theactuation of which gearing is, in turn, limited by a pressure controlledmeans. rlhe gearing is connected with a registeringdevice, and theamount `registered thereby is therefore proportioned to the volume andpressure, and the gas can belmeasured in terms of a unit of constant vaue.

Certain heated or corrosive gases cannot.l`

readily be passed through -a volume registering meter without injurytothe meter, and it is desirous in such cases, and also in other cases, asin gaslines, to measure the volume of gas by the'use of an orificemeter.

Orifice meters are well known in the art, and comprise'merely a plateinserted in the pipe line, which plate has an orifice or open-v ingtherein of known size. t is known that a certain amount of gas at a.given pressure will pass through the orifice in a given time, and thatthe volume passed through will lincrease with the pressure. It istherefore possible to determine the amount of gas passing through theoriidce meter in a given time, it

the average static pressure in the line for the same time is known andthe diderential pressure between the upstream and downstream side isknown, the formula being ln the formula, Q is the quantity in terms oicunits at which the Huid is to be measured and used; C, the co-eiiicientof the orifice; h, the dierential pressure in inches or water; and p,the static pressurein pounds or atmospheres. Where a Pitot tube is usedas a meter, the dynamic pressure is indicated by h, but -the equationremains the same, the

constant C then being the co-ecient of the pipe line.

Heretofore, in using orice meters, it has been the usual'practice tochart, by means of recording gauges, the differential or dynamicpressure/and the static pressure for a given time, as twenty-four hours,and from these charts the average static and di'erential pressures forthat period could be obtained. Knowing the value of the constant B0 C,the average quantity of gas in units of a desired constant value couldbe calculated from the above formula. In similar manner, the quantity ofgas passing through the pipe every ive minutes can be determined, it'the 85 value of C for a period of five minutes is known and the averagestatic and differential pressures for' the live minutes is known. Inpractice, the value of C is usually furnished y the manufacturer of theorifice meter.

According to the present invention, we provide two separate trains ofgearing, each operated from a meter. The actuation of the motor for theiirst train of gearing is controlled by clockwork, and the operation ofthe o'ears is limited by a static pressure controlled means. This firsttrain of gearing drives a tripping mechanism adapted to effect theoperation of the motor for driving the second train of gearing. Thearrangement is such that the higher the static pressure, the morefrequent is the operation of the motor for driving the second train .ofgears.

By this arrangement, the motor for driving the second train of gears maybe actuated several times to each operation of the first motor, thenumber of times the second motor operates being proportional to thestatic pressure. The movement of the second train of gears, which drivesa registering device adapted to register' in units of the desired value,is limited by di'erential or dynamic pressure actuated means, so thatthe amount registered by the registering device with each actuation ofthe second motor is proportional to the differential pressure. rl`henumber of teeth in each train of gears is accurately figured so that theamountl registered will be correct, the second train of gearingincluding gears which correspond to the value of the constant of theorifice meter. lin other words, when the orifice meter has a largeopening, the registering device must be driven to indicate a greaterquantity with each operation of the second motor than when an orificemeter having a small co-efiicient is used, and the gearing in the secondtrain is therefore made properly proportionate to the constant of theorifice meter with which our; invention is to be used. Thus, we haveprovided a registering device adapted to be used in connection withorifice meters which will register the quantity of gas actually passingthrough the meter in units of a constant known and desired value,irrespective of the variations in line pressure and withoutnecessitating the use of recording charts and mental calculations fordetermining this result.

Referring to Figs. 1 and 2 of the drawings, la indicates a pipe linehaving an orifice meter disposed therein at B. rthe upstream side of thepipe is indicated by a, and the downstream side by a. The orifice meter,shown in Fig. 2, comprises a plate b having an orifice or aperture btherein.

rl`he device, as shown in the accompanying drawings, comprises twospaced apart plates 5 and 6, the broken away portion of Fig. Q showingone plate disposed in the rear of the other. vThese plates form a supporting structure and any suitable means could be used in their place.

Mounted at the bottom of plate 5 is a static pressure gauge 7 having anindicator arm 8. Mounted at the bottom of plate 6 is a differentialgauge 9 having an indicator arm' 10. A. pipe 11, leading from theupstream side of the orifice meter B, communicates the pressure on theupstream side of the line to the static pressure gauge through branchvpipe 12 and to one part of the differential gauge through branch 13. 1tis not necessary, however, that the static pressure be taken from theupstream side of the line, as it may be taken from any suitable point inthe line. The downstream side of the differential pressure gaugecommunicates through pipe 14 to the downstream side of the pipe a. Thestatic and differential pressure gauges are of any preferred known oisuitable construction, the static pressure gauge responding to absolutepressure in the line, and the differential gauge being responsive todifferences in pressure on each side of the orifice.

The difference in pressure on the two sides of the orifice increases inproportion to the increase in the velocity of gas passing through theorifice. The pressure gauge is preferably so constructed as to indicatezero pressure at an absolute pipe line pressure of one atmosphere. Inspecial applications where gases below atmospheric pressure are to bemeasured, specially designed gauges would be used.

The indicator arm S of the static pressure gauge is guided betweenparallel segmental strips 15, as shown in Fig. 8, secured to plate 5 andon the top of the indicator arm is a stop member 8a. The indicator arm10 is similarly guided in strips 1G and has a similar stop 10n at itsupper end. The stops 8 and l0a are slid along thc tops of strips 15 and16 respectively, by their respective inrtraeaa dicator arms, but thestrips serve to prevent downward pressure applied to the stops beingtransmitted to the indicator arms.

' Journalled at one side of plate 5, as indicated in Fig. 4, is a shaft20 which passes through the plate 5 and. projects from each facethereof. @n the end of shaft 20 between plates 5 and 6 is keyed an arm21 which projects laterally from between the plates. Near the end of arm21 is -a fixed transverse pin 22. Keyed or fixed tothe end of the shaft2Q is a lateral arm 23 extending in a direction opposite the arm 21.

Near the end of arm 23 is a pin 24. Loose on shaft 20 is a bushing orsleeve 25 which carries a frame 26. A bracket 27'secured to plate 5provides a journal for shaft 2O at 28. The frame 26 may oscillate aboutshaft 20 as its axis. lt extends the greater portion of the distanceacross the plate 5 and is parallel therewith. 0n the side of the framemost remote from shaft 20 is a segmental rack 29 having gear teeththerein, the axis of the segment being the axis of rotation of theframe. 1Within the frame is a serrated curved member 30, the curve ofwhich is plotted to bear a` certain relation to the guide strips 15 forthe indicator arm 8 and to the segmental rack 29. The relation of theframe 26 to the guide 15 and the detailed construction of the frame isclearly shown in Figs. 1, 7 and 8. As shown in Figs. 1 and 4, the frame26 has 'a member 31 thereon extending over pin 24 on arm 23, so thatupward movement of arm 23 lifts the frame 26, causing it to oseillateabout shaft 20. l/Vhen the arm 23 moves downwardly, the frame 26 may,by'gravity, also move downwardly, but its downward movement will belimited by stop 8I on indicator 8 of the static pressure gauge when thecurved serrated portion 30 contacts with the stop. Such limiting of thedownward movement of frame 26 does not, however, prevent the furtherdownward movement of arm 23.

From the foregoing it will be seen that the oscillation of frame 26 islimited proportionately to the position of stop 8a on the pressure gaugeindicator 8. As the indicator 8 is adapted to move toward the right inFig. 1, with an increase in pressure, it can be readily seen that themovement of the frame increases as the pressure increases. In theapparatus shown, it is desired that when the indicator is at the left tothe limit of its movement, it will be at its Zero position. It will moveto this position when the pressure in the line is at atmosphericpressure, that is, zero pressure on the indi- 'cator will actually beone atmosphere absolute pressure.

Journalled in the. plate 5 and passing therethrough is a shaft 35 whichis opposite shaft 20. A bracket 36 secured to the outer face of plate 5forms a journal for one vof the projecting ends of the shaft (see Fig.3). 0n the outer portion of shaft 35 and passing through the journalformed by bracket 36 is a sleeve 37 rotatable about shaft 35. wheel 38which meshes with the -segmental rack 29 on frame 26. 0n the outer endof the sleeve 37 is fixed a ratchet wheel 39. Fixed to the outer end ofshaft 35 is an arm 40 having a small springipressed pawl 41 thereonadapted to engage the ratchet. The arrangement is such that the pawl andratchet will act to rotate yshaft 35 in the di rection of one of thearrows shown in Fig.

3 when the segment 29 is moved upwardly,v

which is the direction of another one of 'the arrows in Fig. 3, but willpermit the ratchet wheel pawl 39 and gear wheel 38 to rotate withoutrotating shaft 35 when the segment is rocked downwardly.

Fixed to the inner end ofshaft 35 between plates 5 and 6 is a ratchetwheel 42 and an arm 43 having a transverse trip pin 44. A pawl 45 issecured to plate 5 and engages ratchet 42 to prevent rotationof theshaft 35 when the gear wheel 38 and sleeve 37 are rotating idly, butpermits rotation of the shaft in the direction of oneof the arrows inFig. 3.

The purpose of the trip arm 43, will be` vhereinafter more fullydescribed. lit may be stated, however, that the gearing 1s such that thenumber. of revolutions of shaft 35 Secured to this sleeve is a gear andtrip arm 43 willv always be the square root of the number of atmospheresabove absolute pressure., lf the indicator 8 and stop 8EL are positionedat zero, which, as heretofore explained, is one atmosphere aboveabsolute pressure and equal to atmospherie pressure, the frame 26 may beswung downwardly so that upon its upward movement, shaft 35 will makeone complete revolution, the square root of one being one. lf the staticpressure is forty-fiye pounds (gauge pressure), approximately sixtypounds or four atmosphere absolute pressure (assuming 15 pounds to equalone atmosphere), the stop 8a will be so positioned that the frame 26-mayrook sufficiently far downward before curved portion 30 contactstherewith tovrotate shaft 35 two complete revolutions upon its beingraised to normal position, two being the square root of four. Theserrations in the curved member 30 prevent the curved portion frommoving the.

stood and need not be specifically describedswf Fluid under pressure isadmitted throufrh pipe 51. A reciprocable rod operated hy the diaphragmis provided at 52, and 53 is a guide for the lower part ot the rod.Pivotally connected with the projecting upper end of rod are links 54which are also connected with arm 21 at 55.

Upon pressure being admitted through pipe 51, rod 52 is moved upwardly,rocking arm 21, rotating shaft 20, rocking arm with pin 24 rdownwardly.The segmental iframe 26 moves downwardly therewith by gravity until itsmovement is stopped by stop 8u. rl`he arm 223 then continues to movedownwardly until rod 52 has been projected to its uppermost limit. Then,as the rod 52 lowers, the diaphragm being weighted, as

atl

commonly done in such motors,v arm 21 is pulled downwardly and arm 23rocked upwardly. When pin 24 engages member 31, the frame 26 is alsorocked upwardly. This i upward movement of the frame 26 must be veryslow in order that trip arm 43 on shaft 85 will not be rotated toorapidly, for i'easons to be hereinafter described.

It is desired that the motor shall operate once every few minutes, suchas three or five minutes. For this purpose, we pro* vide a bracket orothei' suitable supporting means 58 projecting lateraly from plates 5and 6 from a point near the top thereof. Un this bracket is a valvechamber 59 to which luid under pressure is delivered through pipe 60,and with rwhich supply pipe 51 for motor 50 communicates through 1 port61 (see Figs. 1, 10 and 11)..

lVithin the valve chamber 59 is a slidable valve member 62 adapted to bereciprocated across port 61 to establish and cut oli2 the supply ot'fluid to motor 50 through pipe 51. In Fig. 10, the valve is sho-wn inclosed po- `sition, and in Fig. 11 it is shown in open position. rlhevalve is reciprocated by a lever 63 passing' through slot 64 over whichthe valve 62 -forms an air tight seal. The lever 63 pivotally engagesvalve 62 at 65 and it is pivoted at 66. Its lower end is provided with atransverse pin 67.

Depending from bracket 58 is a suitable spring or other motor having atrain of clock gears, which clock is indicatedv at 70. Projecting fromthe clock casing vis a sha t 71 having a cross arm 71 thereon from whichproject pins 72 (see Figs. 2, 10 and 11, the cross arm being dotted inFigs. and 11). Carried oii a suitable support, such as bracket 73, are apair of pivoted levers 74 and 75, both pivoting on a common pin 76. Aspring, indicated at 77, tends to push lever 74 toward the le'ft of theapparatus as shown in Figs. 10 and 11.

Pivoted near the upper end of lever 74 is a pivoted locking lever 78having a shoulder 79 formed therein adapted to engage a pin 7 9 onbracket member 73. As shown in Fig. 10, the notch in lever 78 tends tohold lever 74 in the position shown against the action of spring 77. Thepins 72 ol cross arm 71 are so arranged that as the arm 71 is rotated bythe clock train, they will lift lever 78 until the pin 79 is disengagedfrom the notch or shoulder 79, when spring 77 will force lever 74 to theposition shown in Fig. 11. Pin 67 on lever 63 is so positioned that suchmovement ot the lever 74 moves it a corresponding dis tance to rocklever 63 and open valve 62. On the lower part oit lever 74 is anangularly extending oot or cam 74.

Lever 75 is urged in a direction opposite lever 74 by a spring 80. Alatch lever 81 pivoted to bracket 73 at 82 is provided, this leverhaving a shoulder 83 formed therein for engagement with pin 84 on lever75. At 85 is an angular t'oot on the lever 75.

ri'he operation of the valve mechanism just described is as follows. Theparts are normally in the position shown in Fig. 10, except that lever75 is in the dotted instead of it'ull line position. Fins 72 trip lever78, causing lever 74 to be forced to the left by spring 77, openingvalve 62. The parts will then he in the position shown in Fig. 11. Fluidunder pressure can then passtrom pipe through the valve and through pipe51 t0 the meter 50. As the motor raises arm 217 pin 22 on lever 21engages foot or cam 74 on lever 74 and returns the lever 74 to theposition shown in Fig. 1() without moving lever 63. lVhen the lever 74has been moved to normal position, shoulder 79 on 'locking lever 7 8will engage pin 79 to retain the lever in position. The pin 22 willcontinue to move upwardly past foot 74'l and trip lever 81, disengagingpin 84 'from the shoulder 83, whereupon, spring 8O will move the leverto the full line position shown in Fig. 10. The upper end of lever willengage pin 67 and rock lever 63 to close valve 62. The arm 21 will thenbe at the limit of its upward movement, as indicated in dotted lines inFig. 10, and with the parts in the position shown in Fig. 10.

`When valve 62 is closed, the arm 21 will begin to lower. As it lowers,pin 22 will ride past foot 74a on lever 74, but foot or cam will havebeen projected into the path of pin 22. The pin 22 will engage foot 85and rock lever 75 back to the position shown in dotted lines in Fig. 10and full lines in Fig. 11, and latch lever 81 will hold it in thisposition. The parts are then all automatically set for the next cycle ofoperation. Assuming that shaft 71 rotates a complete revolution everyten minutes, this cycle of operation will be eected once every .liveminutes.

In high pressure lines, the operating fluid for the motor may besupplied to branch pipe 60 from pipe 60a, which communicates with theupstream side ofthe pipe line, as shown in Figs. 1 and 2.

` 'W hen, therefore, arm 97 rocks downwardly,

assenso dournalled in platev 0, but on the side ot the device oppositeshalt 20, is a shalt 90 which corresponds to shaft 20. rlihis sh'attwith its attac-hed parts is shown in detail in liig. 9. rEhe outwardlyprojecting end ot the shalt 90 is jolurnalled in a bracket 91 secured tothe outer iaee ot plate 0. ined to the inwardlyprojecting end ot shaft90 is a laterally extending arm 92 having a transverse pin 93 secured inthe outer end thereof. The construction and arrangement oi this arm issimilar to the arm 21 on shalt 20. e

llotatable on shaft 90 is a trame 94 very similiar in construction to'frame 20. llt is provided with a segmental rack at 95 Vand a serratedcurved portion 90; Like trame 26., the trame moves between the guidebars 10 ot the indicator and its downward movement is limited by stop10L of the diiieren- 'tial gauge indicator 10. With reference to.

2, the indicator is at zero when itis moved as tar as possible to thelett. The curve oi portion 96 is so plotted with refierence to the stop10%1L and to the gear raclr 95, that when the indicator stop 10l is at`aero, the frame may not rock downwardly by reason of curved portion 96contacting with the stop. "lhe trame 94 may beroclred downwardly anincreasing distance with a rise in the diderential pressure. lFiXed tothe shaft 90 is an arm 97 having a pin 98 therein adapted to engage theunder part oit' the trame 94. When the shalt 90 is rotated by lever 92,arm 97 rocks in the oppo site direction. When arm 92 is raised,varm 97rocks downwardly. By reason of the trame 94 being rotatable about shalt90, the weight of supportingthe trame to prevent it trom movingdownwardly rests on pin 98.

the :trame movesdownwardly therewith until the curved portion 90 engagesstop 10l when the arm 97 may-continue to move downwardly withoutfurtherr movement oit the trame 94. Upon the ,arm 97 rising tonormalpositionfpin 98 will engage the under side'oit the trame 94 and littitalso to normal position..

Secured to plate 6 isa suitable iframe or bracket. 100 (see Fig. 5)providing hearings for a shalt 101 on which is a pinion 102 having adefinite number of teeth, which pinion meshes with the teeth on rack 95of the tra-me 94. @n the outer end ot shaft 101 is fixed a ratchet wheel103 (see Figs. 5 and 0). Supported on bracket 100, is a registering o-rmetering device 104 ot any known or suitable construction. 'lhe train otgears in the registering device must bear a certain relation to thenumber ot teeth on pinion 102, this relation depending on the knownco-eficient of the-oriice meter 1B. Shaft 105 is' the driving shalt fromwhich the various indicators are driven.

This shalt projects outside et the Casin and on its end is a cross arm100. At 10 is a ratchet wheel which is fined to the meter casing.

@n one Vend ot the cross :arm 100 is a spring pawl 108 engaging ratchetwheel 103, and on the opposite end is a similar pawl109 engaging fixedratchet wheel 10'?. 'Ehe arrangement isv suoli 'that when shaft 101 isrotated by the downward movement o1 segmental raclr 95, sha-tt 105 will'be held against rotation bv pawl 109 and ratchet 107, but when sha-tt1101 is rotated in the opposite direction hv the upward movement ot therack 95, the rotation will` be transmitted to shalt 105 through erom arm100 and pawl 108. Thus, it will be seen that the registering device willbe operated proportionately to the downward movement o'l trame 94, whichin turn isl'mited by the differential pressure.

rllhe relation oi the teeth on .pinion 102 to the teeth on raclr 95, andthe curvature ot portion n90 relatively to the indicator, is such thatthe rotation imparted to shaft 101 and .to shaft 105 is proportionate tothe square root et the diderential pressure in inches (of water).'l`hus, it 'the diiil'erential pressure is one inch, indicator stop 10awill move :a suihcient distance to permit the frame 94 to be rockeddownwardly sumciently `far that when it Areturns to normal position,shaft 101 will be rotated through. pinion 102, we will assume, onecompleterevolution. When the diderential pressure is twenty-five inches,the vshaft 101 would .be rotated tive complete; revolutions. By

doubling the number ot teeth of pinion 102,

it would be possible to rotate shaft 101 only halt as many times andstill maintain the proper proportional movement. llt is desirable andessential that the shalt 101 be rotated, however, proportionately to thesquareol' thediderential pressure. The relation oit the train ot gearsin the reg1stering device, oit course, depends on the number of timesshaft 101 is geared to'be rotated tora denite increase in pressure.

' For oscillating or rocking the trame 94,

we preferably employ means very similar to that vused tor rocking trame20, rllhis mechanism, as shown, comprises a diaphragm motor 110 suitablysupported near the base of the device. lluid under pressure is suppliedthrough pipe 111 and 112 isa rod reciprocated by the motor, 113 being aguide `tor the lower part oit the rod. Links 114 pivotally connectedwith the projecting upper end of the rod 112 and with arm 92 on shaft 90serve to transmit'the reciprocable movement ot the rod 112 to the arm 97to edect the operation ofi the traine 94.

Motor 110 differs from motor 50 only in that y the former is very quickacting, while the latter, as betere stated, is slow acting.

According to our invention, it is desired that motor 110 operate oncefor every complete revolution of trip lever 43 on shaft 35,

` that is, that the operation of the second .the main supply line 60a at60b (See Figs.

1 and'2). ln Fig. 12, the valve is shown in closed position, and in Fig.13 it is open. Th-e valve is reciprocated by means of a lever 120pivoted at 121 and having one end thereof pivotally engaging the valve117 at 122 through a slot 123 over which the valve l forms an air tightseal. The lower end of lever carries a transversely extending pin 124..

For rocking lever 120 to shift the position of the valve 117, we providelevers and 126 pivoted on pin 127. Lever 125 has an angular foot 125*1and lever 126 has an angular foot 126%. Pivoted at 128 on lever 125 is atripping lever 129 having a small weight 13,0 on one end thereof andhaving its other end extending into the path of travel of tripper arm43. A shoulder 129 on lever 129 is adapted to normally engage a fixedpin 131 on the supporting bracket. Referring to Figs. 12 and 13, aspring 132 is provided for urging lever 125 from the position shown inFig. 12 to the right to the position shown in Fig. 13. On lever 126 is apin 133 and a locking lever 135 pivoted at 131 and having a shoulder 136for engagement with the pin is provided. The full line position of lever126 in Fig. 13 is the normal position of theY lever and corresponds tothe dotted line position in Fig. 12. This lever is urged to the left bya spring,

such as 137.

The operation is as follows. When tripper arm 43 is rotated, pin 44thereon engages the end of trip lever 129, depressing it, the partsbefore such depressing action being in the position shown in Fig. 12,with the exception that lever 126 is in the dotted line position. W'henthe end of lever 129 is rocked downwardly, shoulder 129 is movedupwardly, disengaging pin 131. Spring 132 then acts to move lever 125 tothe position shown in Fig. 13. The upper end of lever 125 engages pin124 on valve actuating lever 120, thereby shifting the valveto the openposition. During this time, lever 126 is stationary.

Upon opening of valve 117 to uncover maratea port 113, motor 110 isactuated, moving lever 92 upwardly and lowering lever 97 in order topermit frame 94 to rock downwardly. Upon the frame 94 reaching the limitallowed by stop 10, pin 93 disengages from contact with the frame 94,and continues to move downward. Cross pin 93 on its upward movementengages 'foot 125Il and thereby rocks lever 125 back to the positionshown in Fig. 12, where weight moves the lever so that shoulder 129engages pin 131. `Lever 120, however, does not more with this movementof lever 125, and arm 92 continues to move upwardly until cross pin 93lifts the end of locking lever 135 when spring 137 forces the lever 126to the :tull line position shown in Fig. 12. The upper end or' thislever, in so moving, engages pin 124 on lever 120 and thereby rocks thelever 120 to close the .valve 117. Then the fluid pressure is cut offfrom motor 110 and arm 92 is moved rapidly downward. ln moving downward,cross pin 93 engages foot or cam 126a and rocks lever 126 to the right,vuntil shoulder 136 on lock lever 135 engages pin 133 to hold lever 126in normal position., rll"he parts are all set then, for thc next cycleof operation. rlhe complete cycle of operation is completed beforetripper arm 43 has rotated another complete revolution, so that a cycleof operation occurs for every revolution ol trip arm 43 and shaft35.

ln order that the device may be substantially automatic, and may, ifnecessary, be run for long periods without winding the clock, we mayprovide an automatic clock winding mechanism, such for instance as thatshown in detail in Fig. 9u. The ordinary winding stem or shaft 14() ofthe clock 70 extends outwardly and fixed on the end ot the shaft is aratchet wheel 1.41. Rotatable about shaft 14() and between the wheel 141and the easing of the clock is a curved arm 142 having a projecting end143. Pivoted on arm 142 is a paw] 14'4 which engages ratchet wheel 141.At 145 is an adjustable pin with which the projecting' end 143 of thearm 142 is adapted to Contact to limit the downward movement or swing ofthe arm. On the opposite end of arm 142 is a'pivoted lever 146, and apin 147 permits the lever 146 to be rocked in one direction only. The.end of lever 146 projects into the path of travel of pin 22 on arm 21.As pin 22 moves upwardly. it engages the projecting end of the lever146` which is held from rocking by pin 147, so that arm 142 isrockedupwardly, and pawl 144, engages ratchet wheel 141 to wind the clock. Thearm 142 may drop by gravity when pin 2 2 lowers until end 143 engagespin 145. Lever 146 provides a dog to permit pin 22 to rock downwardly7if arm 142 is raised so high that it drops before pin 22 Cil lll)

moves downwardly. By proper adjustment pressure stop 2ln moved toa'position to oit pin 145, the proper amount of movement \indicate threeatmospheres gauge pressure ot arm 142 may be obtained. A

From the foregoing, it is believed that the operation ot the inventionmay be understood. The tirst motor is actuated periodically by the clockto rock trame 26 a distance proportional to the square root of thestatic pressure in atmospheres. This, in turn, lcauses the rotation ottrip arm 43 a proportionate distance.v Trip arm 43 in turn effects theoperation ot motor 110 to cause trame 94 to be rocked a distanceproportional to the square ot the differential pressure in inches toreach complete rotation ot the trip arm 43. Such. rocking of' the frame0.4 drives register shaft 105 a known number ot revolutions, and theindicators on tne dials oli the register are accordingly moved toregister va certain amount. The yunits registered by the regulatingdevice are ot constant value.

The operation may be understood more clearly by a specific example.Assume that the orice will pass 100 cubic reet of gas at a pressure of 4ounces in live minutes.

This then is the constant of the orifice meter. ssume that the averagestatic pressure Ifor a given live minutes 1s about three atmospheresgauge pressure, or tour atmospheres absolute pressure. Assume that the'average dilerential pressure for the same period is 25 inches.Accordlngly, the tormula,

`in the example given, would be lliorking the :tormula out this way, wend et the registering de'vice, and that shaft 101 will be rot-ated onceJfor every increase ol" one in the value of the square` root of thedifferential pressure; that is, that shaft 101 (and consequently shaft105) will rotate tive complete revolutions when the dif- :terentialpressure is twenty-five inches-live being the.- square root oftwenty-tive.

Under the circumstances assumed, at the end of a given ve minutes, withthe static (4 atmospheres absolute pressure) and the differentialpressure stop moved to indicate twenty-live inches, the operation willbe as follows: Motor 110 will be operated when the valve is opened bythe clock work and frame 20 will be rocked until it is stopped by stop8". TheI square root ot four is two, so frame 2G will be lowered asufficient distance vto rotate shaft 25 two revolutions when the frameis lifted. llVhen the motor has raised arm 2l to its limit and shut ottthe pressure supply, arm 21 will begin to lower slowly and frame 26, byengagement with pin 24 on arm 23, will be slowly lifted. Shaft '35 willbe rotated slowly, actuating` the vtrip mechanism to cause motor 110 tooperate. Frame 94 will then be rocked downwardly until stop 10a,indicating twenty-tive inches of pressure, prevents further downwardmovement. When the trame is rocked buck, shaft 105 will be rotated tivetimes, and the registering device will register vtive hundred cubicfeet. By this time, frame 26 will have moved sufficiently far to haverotated trip arm 43 a second time., and motor 110 will actuate again tocause shaft 105 to be'rotated another live times, thus moving the dialto indicate 1000 cubic feet, which is the result obtained by use of theformula. At the end of the neXtfive minutes, the operation would berepeated. lf there has been a change in pressure in the line, thepressure controlled stops 8a and 10a will be moved accordingly, and theamount registered would automatically vary. Thus, the average amountpassing through the line every five minutes may be obtained andregistered.,

As before explained, frame 26 will be rocked Suiciently to rotate thetrip arm once even though the static pressure gauge' is at zero. Tttherefore automatically accounts for the difference of one atmospherebetween gauge pressure and absolute pres sure. llt there were nodifferential pressure;7 there would accordingly be no flow of gais. andthe frame 94 wouldl not berocked even though motor 110 would actuateonce.
